HEATING APPARATUS.

Specification of Letters Patent No. 22,760, dated January 25, 1859.

To all whom it may concern:

lie it known that l, Gnoaor, lV. Unmansox, of Scranton, in the county of laizerne, State of Pennsylvania, have invented a new and lmproved Mode of Applying lleat to Rathating-Surfaces; and 1 do hereby declare that the following is a full and exact description thereo'l, reference being had to the accompanying drawings, in whichl igure 1 represents a sectional elevation ol an ordinary cylinder stove, showing the arrangement and application of my im provement. Fig. 2 represents a horizontal section of one line of a steam boiler with my invention applied thereto. Fi 3 represents the front of a tire chamber or fire surface of a locomotive boiler. Fig. it rep resents an exterior elevation of the cylinder stove shown in Fig. 1.

Similar letters refer to similar parts throughout.

A, in said drawings (Fig. 4) indicatesthe ash pit door of an ordinary stove.

B, Fig. 1, represents the tire chamber therein.

C, shows a concavo-convex plate fitted in hearings and abutting against the wall or lining of the said tire chambers; said plate C, has in its center an opening tor the passage of the draft and heat. D, also represents a plate of smaller dimension the space between its rim and the lining of the cylinder serving as the draft passage.

(1 I), and G I), Fig. 2, shows a series of plates constructed and arranged in accordance with my invention and applied to the flue of a steam boiler. These plates (1 and I) may be flat or plain.

l Fig. *1, shows the door of a tire chamber of an ordinary cylinder stove.

The object of my invention is to generate a greater amount of heat with. a given quantity of fuel than by any other mode now in use, and to control and govern said heat in its application to fire chambers, smoke lines and steam boilers by the means hereinafter described.

The nature of my invention consists in so arranging within a tire chamber, smoke tine, or steam boiler a series of plates as that the heat will in its passage, be delayed or retarded as it were. within combustion chambers, Formed by said plates, and thereby throw oil or give out a much greater amountof heat and with fuel than by any tice.

My said improvement is alike applicable to stoves for household use and to furnaces, l steam boilers and locomotives and to all mauutacturiug establishments where economy of Fuel an object. I To enable others skilled in the. art to make and use my invention, t will proceed. l toa description of its construction and oper y ation. Fire being started in the firebox or chamber a current of heat is transmitted through i the opening in the center of plate C, and in its onward passage is expanded by the next plate I). which detlects said current against the sides of the fire chamber and passes through between it and the rim or edge of i said plate I). and so to the exit flue, said 'current is alternately expanded which ar l i l a much less quantity of other method now 111 pracraugement compels the giving ott' a greater amount of heat by reason of the deflection against the sides of the cylinder of the heat ed current within the series of combustion chambers. The said plates turn on their bearings.

lly the application of my invention it will be evident that a great saving will be eftected in the consumption of fuel and that the draft so essential in furnaces, is not impedeil but on the contrary enhanced, as well i as placing a certain guide in the power of l the attendant to control and govern the l amount of heat or steam required. It has long been a desideratmu, with railroad companies especially, to economize the consumption of fuel in locomotives, and the t same will apply to all who use motive power and require the agency of a simple, cheap 1 and unfailing substitute for the present 0bjectionahle mode of construction. I By the application of my nnprovement r the motive power of a steam engine will be generated by the use of one fourth the quanl tity of fuel now used; and by its use no impediment is otlercd to the passage of the draft, which evil has hitherto been an obstacle to the successful working of the many ailiiiis which heretofore have been devised l for reducing the first cost of motive power. My arrangement of plates with draft pas Y ages alternative tirst through the center of one plate and then between the edge of the lit) succeeding plate and the wall of the fire chamber furmshes the (lesn'ed means of 0bviatmg the defects alluded to, and that too with :1 reduction oil? at least two thirds of the qnnntit of fuel now neees ary to erente the reqnieite moi ive power.

Having described the nature and operation of my invention, wish it, distinctly nnlleretoetl that I do not claim dampers o1? to he the inventor of :1 eomlmstion chamber,

What 1 (lo claim and desire to secure by Letters Patent is- The nppliezttien to tire elmmhers or smoke llnes, ol? :1 rlouble series of plates when the ezlme are, eonstrneteeh combined and 211'- rungetl, in the manner and for the purpose hereinhefore set forth.
